Damping seat for mining motor

Abstract

The utility model discloses a damping seat for a mining motor. The damping seat comprises a damping shell, two springs, two sliding discs, a sliding rod, a rocker and a fixed disc, the damping shell is fixed to the horizontal plane, a sliding rod is installed in the damping shell and located on the lower portion of the damping shell, the two sliding discs penetrate through the sliding rod, springsare arranged between the sliding discs and the damping shell, one ends of the rockers are hinged to the sliding discs, the other ends of the rockers are hinged to the fixed disc, and the two rockersare arranged in a splayed shape. The motor is fixed to the fixed disc through a fastener, and when the motor works, damping of the fixed disc in the vertical direction is achieved through the two sliding discs and the compression springs on the two sides. The damping seat is simple in structure and good in damping effect.

Description

technical field [0001] The invention relates to mining equipment, in particular to a shock-absorbing seat for a mining motor. Background technique [0002] At present, there are many kinds of motor shock-absorbing bases, but their function is to reduce the vibration of the motor in the vertical direction, and cannot reduce the vibration of the motor in the horizontal direction; at the same time, it cannot reduce the vibration caused by the instantaneous torque generated at the moment of motor startup. At the same time, the vibration problem caused by the instantaneous torque generated at the moment of starting the motor is not easy for those skilled in the art to consider. [0003] In the prior art, there have been relevant researches on reducing the vibration of the motor, mainly by setting anti-vibration materials under the base of the motor, but the anti-vibration effect is not ideal. Or some directly fill the cavity between the rotor and the stator with rubber. If the v...

[0002] At present, there are many kinds of motor shock-absorbing bases, but their function is to reduce the vibration of the motor in the vertical direction, and cannot reduce the vibration of the motor in the horizontal direction; at the same time, it cannot reduce the vibration caused by the instantaneous torque generated at the moment of motor startup. At the same time, the vibration problem caused by the instantaneous torque generated by the motor at the moment of starting is not easy for those skilled in the art to consider

[0003] In the prior art, there have been relevant researches on reducing motor vibration, mainly by installing anti-vibration materials under the motor base, but the anti-vibration effect is not ideal

Or some directly fill the cavity between the rotor and the stator with rubber. If the volume of the cavity is large, the volume of the filled rubber is also large. Under the high-speed rotation of the motor, the rubber with a large volume is easy to produce Deformation will seriously affect the rotation of the rotor. When suppressing vibration, it is easy to cause the generator to stall and the vibration reduction effect is poor.
